FIG. 1 is a front view of a display screen portion with a transitional graphical user interface component showing a first image in a sequence of a first embodiment of our invention;

FIG. 2 is a front view of a display screen portion with a transitional graphical user interface component showing a second image in the sequence of the first embodiment of our invention;

FIG. 4 is a front view of a display screen portion with a transitional graphical user interface component showing a second image in the sequence of the second embodiment of our invention.

The subject matter in this patent includes a process or period in which an image changes into another image. This process or period forms no part of the claimed design.

The stippling and gray regions in the drawings indicate contrasts of appearance. The elongated line, broken in part, which extends along a lower margin of the card, is part of the claimed design.

The longer-incremented broken lines showing of a portion of a display screen of a communications terminal illustrate environment and form no part of the claimed design. The text shown in finer-incremented broken lines illustrate features that form no part of the claimed design, and are intended to illustrate an optional, environmental information which can be omitted, with the underlying surface being continuous and uninterrupted from its immediately surrounding area. 

CLAIM The ornamental design for a display screen portion with a transitional graphical user interface component, as shown and described.
